Bern's most popular women's bike helmet provides superior protection for those of you who don't want a Styrofoam planet on your head. Whether commuting to work in traffic or riding for a cause, we can't promise zero helmet head when you reach your destination, but we can promise to keep you safe and stylin' on your journey. Bern's exclusive Zipmold foam is a liquid foam injection process that provides a better weight to strength ratio so Bern can provide customers with a lighter, lower profile helmet. Zipmold hard foam meets ASTM F 2040, CPSC and EN 1078 standards for bike and skate.
